[aspectwerkz-user] Questions on Aspects and Annotations

Hello there! I'd like to know what I'm doing wrong here. I've defined this
task:
<taskdef name="awc" classname="
org.codehaus.aspectwerkz.compiler.AspectWerkzCTask"
classpathref="aspectwerkz-path"/>
<target name="compile-aspects" depends="init">
        <awc verbose="true" classpathref="project.class.path">
            <target path="bin"></target>
        </awc>
    </target>

But, it seems that its not compiling any aspects I've wrote. What could be
the problem?

Regards
